In this post I will share the files I used for my presentation called blender challenges.
But first I have to apologize for posting a short blogpost, my wife is here and we are going to visit Amsterdam for 2 days, so not much time for writting 
This was one of my best conference, if not simply the best! Got the chance to meet a lot of new people, especially some swiss guys this time too! Hope we can do some gathering one day soon.
Apart from meeting people (which takes some time and even makes you miss some talks because chatting and sharing is so much fun) you also get the chance to see talks and presentation of techinques, researches or simply showcases of what people do with blender.
Blender Challenges
I had the chance and task to host the open-stage time slot, and so decided to share some files and problems encountered during some productions, but in a simplified way. It resulted in a series of 6-7 .blend files, with something wrong in them, and people would need to solve them.
The files were handed out at start of the talk, and folks had to gather in groups and try to solve them. The few first ones were rather easy, ranging from bad oriented normals, to overlaping faces. some others were a bit more tricky. The audience was very participative and it started some nice discussion and trick sharing, I loved it.
Instead of giving out the answers, I will give out the files for your pleasure and you can try to solve them.
Here is the link: http://dl.dropbox.com/u/6506660/challenges_2011.zip (1.1 mb)
I hope you can enjoy them as much as the audience did
Can you solve them ? Do you have some answers ?
Do not read the comments if you dont want to be spoiled

J’ai beaucoup apprecié ton intervention a la Bconf,
et comme promis j’ai un petit Challenge pour toi,
(moi j’ai pas la solution, peut etre c’est un BUG?)
J’ai les trois objects
ARRAY_OBJ, Start_OBJ et End_OBJ avec 3 materiels differents JAUNE ROUGE et BLEU
Je crée un array selon la longuer d’une curve,
et j’ajoute le modifier curve, dans le modifier ARRAY,
je donne un objet de depart et de fin a l’array,
le probleme a resoudre est pourquoi je perd les materiels
des object de depart et de fin?

I really appreciated your presence to the Bconf,
and as promised I have a small Challenge for you
(I have not the solution, it can be a BUG?)
I have three objects
ARRAY_OBJ, and Start_OBJ End_OBJ with 3 different materials
and BLUE RED YELLOW
I create an array according to a long curve,
and I add the curve to change, change in the array,
I give an object a start and end the array,
the problem to solve is why I lost the material of original goal and purpose?
